Abstract: We observe space dispersive, second harmonic green generations from a 2D QPM-periodically poled LiNbOl pumped by a NdYAG laser. The angular-tuning and phase-matching temperature analyses reveals a simultaneous quasi-phase-matching mechanism up to five reciprocal lattice vectors in the 2D x(') nonlinear photonic structure of tetragonal symmetry. 02003 Optical Society of America OCIS codes: (190.400) Nonlinear optics materials; (160.3130) LiNbO,
